Billionaire investor Bill Ackman has identified Amazon as a fundamentally undervalued enterprise, significantly boosting his investment in the company during a period of market instability in April. His investment firm, Pershing Square Capital Management, which has outperformed the S&P 500 significantly this year, sees immense potential for prolonged expansion and enhanced profitability within Amazon's diverse business segments. This strategic move underscores a belief in Amazon's resilience and its capacity to deliver substantial returns, driven by its leadership in both cloud services and retail logistics, even as the market grapples with economic uncertainties.
Bill Ackman, a notable figure in the investment community, has made headlines with his fund's impressive 22.9% return by the end of August 2025, far exceeding the S&P 500's 10.8% gain. His investment philosophy centers on capitalizing on market downturns when quality assets are temporarily undervalued. Ackman's recent move to acquire additional Amazon shares came amidst a tariff-induced market sell-off in April, which he viewed as a prime opportunity. He liquidated Pershing Square's position in Canadian Pacific Kansas City to fund this significant investment, adding Amazon to an exclusive portfolio that already includes a substantial holding in Alphabet.
Ackman acquired Amazon shares at a forward earnings multiple of 25, a valuation he considered exceptionally favorable. Despite subsequent appreciation in Amazon's stock price, he maintains that the company remains undervalued, projecting considerable upside due to its capacity for sustained high earnings growth. His confidence is rooted in Amazon's dual strengths: its formidable retail operations and its dominant cloud computing platform, Amazon Web Services (AWS).
AWS stands out as the world's leading public cloud provider, boasting an annual run rate of $120 billion and an impressive 37% operating margin. This segment's growth trajectory is further fueled by burgeoning demand from artificial intelligence applications, which currently outstrips Amazon's rapid capacity expansion efforts. Ackman anticipates a long-term shift where cloud computing will host 80% of IT workloads, a significant increase from the current 20%, positioning AWS for massive future growth.
In the retail sector, Amazon's extensive selection and highly efficient logistics network provide a substantial competitive advantage. The company's continuous investments in its supply chain and warehouse technology are actively reducing per-unit shipping costs, exemplified by a 5% reduction in the last quarter. Ackman foresees a potential doubling of Amazon's retail profit margin from its current 5%, translating into enormous profits from its $550 billion retail business. These operational efficiencies and economies of scale are expected to drive significant profit margin expansion across both core businesses.
Ackman's long-term bullish stance on Amazon is based on its established leadership in critical, high-growth industries. Even after a recent price surge, the stock continues to offer compelling value for investors seeking exposure to powerful market trends in e-commerce and cloud technology. Amazon's strategic positioning and ongoing innovation promise continued financial outperformance and shareholder value.
